BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a configuration diagram of a web screen evaluation system 10 according to an embodiment of the present invention. In the WEB screen evaluation system 10 according to the present embodiment, a plurality of subjects perform an operation using a mouse or a keyboard on the WEB screen to be evaluated, accumulate the operation contents, and determine whether the WEB screen is easy to use. Output the evaluation result. In this specification, elements to be operated by operation means such as a mouse and a keyboard, such as various buttons, check boxes, and input fields displayed on the WEB screen are referred to as operation target elements.
[0009]
In FIG. 1, a WEB screen evaluation system 10 is constituted by a computer such as a personal computer, a program execution unit 12 including a CPU, a storage unit 14 including a ROM, a RAM and a hard disk device, and a display device 15 such as a CRT and a liquid crystal. And a mouse 16 and a keyboard 17 as operation means. In addition, other pointing devices such as a trackball and a trackpad may be used as the operation means in addition to the mouse and the keyboard.
[0010]
The storage unit 14 stores, for example, an operating system (OS) 18 such as WINDOWS (registered trademark), a WEB screen editing program 20, a browser program 22, an operation detection program 26, and an evaluation program 28 that operate on the OS 18. Have been. Then, the function as the WEB screen evaluation system 10 is realized by the program execution unit 20 executing these programs 20 to 28 on the OS 18.
[0011]
The web screen editing program 20 is a program for creating and editing web screen data in a screen description language such as HTML. As the web screen editing program 20, for example, a commercially available web screen creation program or the like can be used. In the present embodiment, the WEB screen is created and edited by the WEB screen editing program 20 on the WEB screen evaluation system 10. However, the WEB screen is created and edited by another computer, and the WEB screen is edited. A configuration in which data is taken into the WEB screen evaluation system 10 may be adopted.
[0012]
The browser program 22 is a program for reading WEB screen data created and edited by the WEB screen editing program 20 and displaying it on the display device 15 as a WEB screen. As the browser program 22, for example, a browser program for browsing the Internet, which is provided as a standard feature in a commercially available personal computer, or the like can be used.
[0013]
The operation detection program 26 detects a mouse operation or a keyboard operation performed on the WEB screen displayed on the display device 15 by the browser program 22. More specifically, the operation detection program 26 detects a click operation, a pointer movement operation, and a scroll operation in the display window of the WEB screen by the browser program 22 using a system call of the OS 18, for example. Further, since a mouse click operation and a scroll operation can be performed on the keyboard 17 (for example, pressing an Enter key or pressing a PageUp key or a PageDown key), such a keyboard operation is also detected. Then, these detection results are notified to the evaluation program 28 as operation content information.
[0014]
As described below, the evaluation program 28 activates the operation detection program 26, and accumulates and outputs each operation content item based on the operation content information notified from the operation detection program 26.
[0015]
FIG. 2 is a flowchart of the evaluation program 28. As shown in the figure, first, for the WEB screen to be evaluated, the click order of each operation target element assumed by the screen designer, the pointer movement trajectory length between each operation target element, and the like are input (S100). . For example, it is assumed that a web screen as shown in FIGS. 3A to 3C is to be evaluated. 3 (a) to 3 (c) show screen transitions in the case of logging in to an Internet banking site and inquiring the balance of an account. The "login" button (button A) in FIG. When the button is clicked, the screen transits to the main menu screen shown in FIG. 6B, and when the “Balance Inquiry” button (button B) is clicked on the main menu screen, the screen transits to the balance inquiry screen shown in FIG. When the account selection check box (check box C) is checked on the balance inquiry screen and the “OK” button (button D) is clicked, the balance of the checked account is displayed. In the case of such a screen, the following input is performed as the click order and the pointer movement trajectory length.
[0016]
Click order button A → button B → check box C → button D is input as the click order.
[0017]
Pointer movement trajectory length button A → trajectory length L1 of button B, button B → trajectory length L2 of check box C, and check box C → trajectory length L3 of button D are input.
When there are a plurality of check boxes C as shown in FIG. 3 (c), an average value of the check boxes may be input, or the trajectory length is input assuming any of the check boxes. You may do so.
[0018]
When the evaluation start operation is performed after the above input is performed (S102), the web screen data is read out by the browser program 22 and displayed on the display device 15 (S104). Next, the operation detection program 26 is activated, and operation content information indicating a click operation, a pointer movement operation, and a scroll operation performed on the WEB screen is acquired (S106). Then, based on the operation content information, the operations performed on the screen are cumulatively totaled for each of the following items (1) to (4) (S108). The evaluation program 28 detects the coordinate range of each operation target element included in the screen based on the WEB screen data, and determines which operation is performed based on the positional relationship between the coordinate range and the click operation position on the screen. It is determined whether the target element has been clicked or a click operation has been performed at a position that is not the operation target element.
[0019]
(1) Number of erroneous click operations: Counts the number of erroneous click operations (hereinafter referred to as erroneous clicks) at positions other than the operation target element on the WEB screen. At this time, for example, the screen may be divided into a plurality of regions, and the number of erroneous clicks may be accumulated for each region, so that it is possible to grasp which part of the screen is likely to be erroneously clicked.
[0020]
(2) Incorrect click order: Accumulates the number of click operations performed in an order different from the assumed click order (hereinafter referred to as an incorrect order click). When the correct order is button A → button B → check box C → button D as in the example of FIG. 3 described above, the number of click operations performed contrary to this order is accumulated for each incorrect order. For example, when an incorrect order click such as button B → button D or button B → button E is performed, the number of times is individually accumulated for each of button B → button D and button B → button E.
[0021]
{Circle around (3)} pointer movement trajectory length: accumulates the length of the movement trajectory of the pointer between continuously operated operation target elements. For example, when a click operation in the order of button A → button B → check box C → button D is assumed as in the above example, button A → button B, button B → check box C, and check box The movement trajectory length between each of the C → button D is individually accumulated.
[0022]
(4) Screen scroll amount: The number of screen scroll operations is cumulatively counted.
[0023]
When the operation on the WEB screen is completed (S110), it is input whether another subject is to perform the operation continuously (S112), and if the operation is continued, the process returns to S104. On the other hand, when ending the evaluation test, the evaluation results accumulated as described above are output (S114). That is, the evaluation result of the operability of the WEB screen is output to the screen for each of the following items: (1) the number of erroneous clicks, (2) the number of erroneous order clicks, (3) the pointer movement trajectory length, and (4) the screen scroll amount. Alternatively, print output or file output is performed as necessary.
[0024]
The designer of the WEB screen can judge the operability of the WEB screen based on the output evaluation result. For example, when the number of erroneous clicks in (1) or the number of erroneous order clicks in (2) is greater than a predetermined number, or the length of the pointer movement trajectory of (2) or the trajectory length of the scroll amount of (4) If it is larger than the scroll amount, it is determined that there is room for improvement in the operability of the WEB screen. If it is determined that there is room for improvement, the configuration of the WEB screen is modified, and the modified WEB screen is again subjected to an evaluation test by a plurality of subjects in the same manner as described above to improve operability. Check if you did. For example, operability is improved when any of (1) the number of erroneous clicks, (2) the number of erroneous click operations, (3) the length of the movement locus of the pointer, or (4) the scroll amount decreases. It can be determined that it has been done. By repeating such evaluation and correction of the WEB screen, a more usable WEB screen can be designed.
[0025]
For each evaluation item of the WEB screen (that is, the number of erroneous clicks, the number of erroneous clicks, the pointer movement trajectory length, and the scroll amount), a method of correcting the WEB screen that has been effective in improving operability is accumulated. , An effective correction method may be recommended. That is, regarding the method of correcting the WEB screen, for example, when the WEB screen is corrected based on the evaluation result, the WEB screen is classified into several sections such as replacement of a button position, change of a button size, change of a background image, and the like. The user inputs the evaluation item and the type of the type of correction that are the reason for the correction. For example, when the number of erroneous clicks is larger than the predetermined number, and the button positions are exchanged, the evaluation item: “the number of erroneous clicks” and the modification category corresponding thereto: “button position exchange” are input. When the evaluation result is improved as a result of the modification of the WEB screen, the modification section is recorded as an effective modification means. By accumulating such effective correction means, a correction category recorded with high frequency for each type of evaluation result is recommended as an appropriate correction method.
[0026]

The system according to the present embodiment includes an operation computer 100 for operating a web screen and an evaluation computer 102 for evaluating the operability of the web screen based on the operation content. Among them, a plurality of operation computers 100 are provided so that evaluation tests by a large number of subjects can be performed simultaneously in parallel.
[0027]
Each operation computer 100 is connected to the evaluation computer 102, and the evaluation computer 102 collects data indicating an operation on the WEB screen from each operation computer 100, and performs the same operation as in the first embodiment. The evaluation result is output for each evaluation item such as the number of erroneous clicks and the length of the pointer movement locus.
[0028]
